Fire tube boilers series KCVa-(ECO)

KSVa series (ECO model) steel automated fire-tube hot-water boilers are designed for heating and hot water supply to residential, industrial and office buildings in the closed heat-supply systems. The essential difference of ECO type boilers from the similar mass-produced fire-tube boilers is use of multi-layer internal thermal gastight front door, and special heat-resistant concrete, developed with the participation of specialists of the Kiev National University of Construction and Architecture. This modernization allowed increasing life span and time between overhauls for boilers.
